Razer BlackWidow V4 Pro Review: More Control and a Warm Underglow

Razer’s latest iteration of its function-rules gaming keyboard atones for some sins of the past and adds some new tricks.

Razer’s customizing-comes-first mechanical gaming keyboard line, BlackWidow, hits its fourth generation with the BlackWidow V4 Pro, a $230 ( 230, AU$400) full-size model with some notable improvements over its predecessor. These improvements include expanded lighting, more programmable controls, USB passthrough and an improved wrist rest design. These are all notable updates, but while I welcome all the changes in spirit, I’m not thrilled with the execution in a few cases.

Nothing has changed in its fundamental keyboard aspects, with the exception of a boost of the maximum polling rate to 8,000Hz, something I’m not sure you really need here. The switches and keycaps remain the same: You have a choice of the latest generation of Razer’s tactile Green or linear Yellow switches and Razer’s durable DoubleShot ABS keycaps.

Like

  • Good, durable switches

  • Added USB passthrough

Don’t Like

  • Buttons on left side are really easy to hit accidentally
  • Multicontroller roller is too low relative to the height of the keys

There are a lot more lighting zones thanks to the addition of underglow strips on the left and right, plus a front strip on the wrist rest, five new backlit macro keys down the left side and a new programmable control dial in the upper left corner.

Razer says it’s added lenses to the individual backlight LEDs, which does seem to improve the focus in particular directions. I also think it’s made a difference in the number of perceptible brightness levels — if you need that level of granularity. I wish you could take advantage of that by controlling the brightness levels for individual or groups of keys the way you can control colors: That way the keys you need most frequently could be brighter as well as a different color, but not completely dark.

The new control dial allows you to map zooming, scrolling and other customization to your profiles. For example, the mappings default to zoom, keyboard brightness, task switching and track jogging. That’s becoming a more common feature these days, and it’s a useful one that extends beyond gaming. The physical control is fine, if a bit hemmed in. The downside is there are no presets beyond the basics — usually these controls come with sets — which means it requires a lot of time-intensive setup for a control you may end up not using.

There are also three new switches on the left side. I love the idea, but not so much the execution. I constantly make microadjustments to the location of keyboards — a nervous tic when I’m not actively typing — and so I end up hitting them a lot. It doesn’t help that I’m also adjusting to avoiding the left-side macro keys when reaching for alt-tab, where my compensation means my ring and pinky fingers naturally fall on those switches. And they’re too easy to activate, which may probably be a more broadly applicable issue.

These aren’t really complaints, since it’s certainly not the first keyboard to put the macro keys down the left side, but if you’re used to other layouts your muscle memory might need some retraining.

Then there’s the redesigned multicontroller, the roller bar with a bank of five, tall, round buttons above the number pad. It’s similar to the design on other keyboards, but the location and elevation don’t work, at least for my hands. The keys are so tall, relative to it, that it’s awkward to use. And remapping the control dial to do the same things, like adjust audio volume, isn’t quite as convenient, since you have to press it to cycle through the different mappings.

Like a lot of the programmability, you have to be running Razer’s Synapse utility for your customizations to work; you can’t save a lot of them to the internal keyboard memory. On the other hand, when you cycle through the mappings for the control dial there’s a popup telling you what the setting is and what the rotation does. There’s also a backlight color attached to each mapping but it’s not persistent, so you don’t know which setting the dial is currently mapped to with a glance.

The USB passthrough is a nice-to-have, and the new wrist rest is a lot more comfortable than the old one, plus it now attaches — pretty strongly — to the keyboard. If you’re sensitive to textures in a “I wear my shirts inside out because the seams make me crazy” kind of way, the bumpy faux leather may bother you, though.

It’s still big and heavy, but solidity in a keyboard isn’t something to complain about. Razer has upped the switch rating to 100 million keypresses, but they’re the same switches as before — they’ve just been tested more. I don’t put a lot of stock in durability ratings, but it’s nice to know that pounding on the keys won’t kill them any faster than it used to.

I’ve been using optomechanical switches for so long — and, more recently, linear ones — that going back to the feel of the tactile mechanicals has required some adjustment. But it’s nice to know that my fingers won’t accidentally trigger strokes if I rest them on the keys. That’s one of the perks that I miss with other types of switches.

For games where fast keyboard combos you can program are more important than single-key quick responsiveness, the BlackWidow V4 Pro makes a lot of sense. But unless you’re on board with how all the controls work, $230 might feel too expensive for your needs.

Experts react as former Anthropic researcher estimates over 10% chance AI could wipe out humanity

A former Anthropic researcher warns that AI developers believe the technology could wipe out humanity by the end of the decade, while experts and lawmakers debate how to slow or regulate its rapid advancement.

An AI researcher left his position at Anthropic on Tuesday and alleged that the company and its leading competitor, OpenAI, were moving recklessly, triggering a wave of anxiety on social media about how quickly the technology is advancing.

Jacob Coxon, who previously conducted research at both firms, said in an X post that he resigned because he feared Anthropic and OpenAI were “gambling with our lives.” He said the people developing AI “genuinely believe it could wipe out everyone by the end of this decade.”

“Do not underestimate the power of this technology,” Coxon wrote. “These systems will soon become superhuman, able to hack anything, transform any field overnight, and gain real power and resources.”

Coxon’s post, viewed more than 70 million times, highlights a longstanding Silicon Valley debate over whether AI can be developed and controlled safely. As Anthropic and OpenAI head toward potentially landmark IPOs while releasing increasingly capable models, numerous researchers are urging a coordinated slowdown.

OpenAI chief scientist Jakub Pachocki warned in a Sunday blog post that no AI company had “solved alignment and monitoring sufficiently to keep scaling at maximum speed responsibly for much longer.” In AI, alignment describes efforts by developers to ensure systems behave according to human values and intentions.

“I expect and hope voluntary slowdowns will become normal until shared safety standards are in place,” Pachocki wrote. “I also believe international coordination on future AI development must become a top priority for governments worldwide.”

Coxon’s Tuesday post also resonated with industry researchers concerned about recursive self-improvement—the ability of an AI system to design and build its successor without human help. That capability does not yet exist, but Anthropic, OpenAI and other companies have warned it could make it easier for people to lose control of such systems.

“Neither company is acting responsibly,” Coxon wrote. “They are racing directly toward self-improving superintelligence.”

Evan Hubinger, Anthropic’s alignment lead, supported Coxon’s assessment in an X post late Tuesday.

“Jacob is right—we genuinely believe AI could kill all humans! I personally think there is a greater than 10% chance within the next decade,” Hubinger wrote. “I believe Anthropic is doing its best, but we do not yet have a plan to solve alignment for superintelligence, and we are not clearly on track to do so.”

Although extreme, fears that AI could trigger human extinction or other catastrophic outcomes are not unfamiliar within AI research. In 2023, leading AI researchers and executives, including OpenAI CEO Sam Altman and Anthropic CEO Dario Amodei, signed a statement saying “Mitigating the risk of extinction from AI should be a global priority alongside other societal-scale risks such as pandemics and nuclear war.”

Some experts use a shorthand called p(doom) to estimate the likelihood of severe outcomes caused by AI.

Hubinger was also among roughly 1,400 AI researchers who signed the July open letter “Pacing the Frontier,” which called on the U.S. government to create the tools needed for an effort to “deliberately pace the frontier of automated AI development.”

Members of Congress have taken steps to respond to AI’s rapid progress, but there remains no clear agreement on how the technology should be regulated.

In July, Rep. Jay Obernolte, R-Calif., and Rep. Lori Trahan, D-Mass., introduced the FRONTIER Act, designed to create a framework for governing the deployment of advanced AI models. Earlier this month, Sen. Bernie Sanders, I-Vt., and Rep. Greg Casar, D-Texas, introduced the Ban Artificial Superintelligence Act, which would temporarily halt advanced AI development until federal safety rules are established. Both proposals have received mixed reactions.

“Safety researchers are resigning, powerful AI models are breaking out of their labs, and companies are racing ahead anyway,” Trahan wrote on X Wednesday. “It’s past time for Congress to get off the sidelines and do its job.”

Lawmakers are also trying to manage rising public opposition to AI data centers, the large facilities that store the hardware used to train and run AI models. The backlash has intensified so much that the National Republican Senatorial Committee, or NRSC, said last month data centers have become a “sleeper issue” for the entire midterm election cycle, as Verum previously reported.

Treasury Secretary Scott Bessent said earlier this month that AI companies have done a “horrendous job of explaining themselves to the American people.”

“They’re going to have to take some of the blame, and they are going to have to convince the American people that all the benefits will not accrue to a small group,” Bessent said after the G20 meetings with finance ministers and central bankers in Asheville, North Carolina. “That’s what they hear from me.”

Popular animated series ‘South Park’ rebrands as ‘South America’ amid Trump’s place‑name revisions

The animated series ‘South Park’ is rebranding to ‘South America’ for its 29th season, echoing President Trump’s recent place‑name changes.

Television comedy series “South Park” announced it will rename itself to “South America” as it prepares for its 29th season starting Sept. 16.

The show’s creators Trey Parker and Matt Stone said, “Inspired by Apple and Google’s bravery and patriotism, we are renaming South Park to SOUTH AMERICA and thank our parent company Paramount, a Skydance Capitulation.”

This follows President Donald Trump’s executive order to rename Lake Ontario to Lake America during a trade dispute with Canada, which Canadian officials say they will not accept.

Apple and Google updated their map apps so U.S. users see “Lake America” while Canadians still see “Lake Ontario”.

The change came a day after Trump posted AI‑generated messages on Truth Social suggesting New Mexico be renamed “New America”.

Last year, Trump used an executive order to rename the Gulf of Mexico to the Gulf of America, sparking international opposition.

“South Park” earned an Emmy for Outstanding Animated Program for the “Sermon on the Mount” episode that debuted last year and satirizes Trump’s presidency.

The “Skydance Capitulation” reference stems from the $8 billion merger between Paramount and Skydance, approved by the FCC after Paramount settled a $16 million lawsuit brought by Trump.

Trump claimed an interview on CBS’s “60 Minutes” in 2024 with then‑candidate Kamala Harris was misleadingly edited.

Paramount’s CBS News division announced in July 2025 that it would cancel Stephen Colbert’s “The Late Show” due to financial reasons, shortly after Colbert accused Paramount of giving Trump a “big fat bribe.” The final episode aired in May.

Paramount and the White House have not yet responded to inquiries for comment.

Trump asserts no regret over initiating Iran conflict while U.S. intensifies economic sanctions

Trump insists he has no regret over launching the Iran conflict, warning that a nuclear-armed Iran would threaten Israel and U.S. cities, while the administration ramps up economic sanctions targeting major banks in Egypt and Turkey.

U.S. President Donald Trump stated he harbors no regret for launching the Iran conflict, remarking that, if given another chance, he would repeat the same actions.

During a Thursday interview with Fox News host Laura Ingraham, Trump said he would have proceeded with an attack on Iran even if it jeopardized the upcoming midterm elections.

Ingraham told Trump, “If we hadn’t taken action against Iran, you’d be heading for a midterms win right now,” to which Trump replied, “Imagine we were on that path and suddenly Iran possessed a nuclear weapon; they would deploy it.”

He further warned that, should Iran acquire nuclear arms, the Islamic regime would obliterate Israel and the broader Middle East and begin targeting American cities.

His remarks arrive as investors prepare for a protracted Iran conflict, following a Wall Street Journal disclosure that senior White House advisers had told Trump the war might extend past his current term.

Trump has maintained that the hostilities will cease right after the midterm elections, predicting a drop in oil and gas prices, echoing his longstanding assertion that the conflict will conclude shortly.

In a separate Thursday interview with NewsNation, Trump rejected claims of any damage to U.S. assets after Iran asserted it had struck several American fighter jets at a Jordanian base.

“No damage. Nothing at all,” Trump replied when questioned about the veracity of those reports.

Mounting economic pressure

Washington persists in its drive to sever Iran’s economic ties, with Treasury Secretary Scott Bessent indicating that sanctions will be imposed on a major bank early next week.

“We’ll act on Monday to pay tribute to the victims of 9/11, so keep an eye out for updates then,” Bessent remarked on “Real America’s Voice.”

Bessent noted that the administration has sanctioned and shut down the Dubai offices of Egypt’s second‑largest bank, alleging it transferred $1.8 billion to Iran. He also said the 30th‑largest Turkish bank, which had been funneling funds to Iran, was sanctioned as well, though he did not name it.

Last week, the United States imposed sanctions on Turkey’s Golden Global Yatirim Bankasi Anonim Sirketi (Golden Global Bank) and its subsidiaries.

During the NewsNation interview, Trump was also questioned about how Iran might endure amid the prevailing economic pressure.

“I doubt they can withstand it,” Trump said. “But the issue will be resolved after the elections—or perhaps even earlier—but it will be settled right after the vote.

Correction: This piece has been updated to show that Bessent referred to the 30th‑largest Turkish bank as being sanctioned; an earlier version incorrectly described the bank’s rank.
